Equivalent & Substitute Parts for PH10-12R-E

Part Overview

The PH10-12R-E is a ring terminal connector manufactured by Panduit Corp, designed for 10-12 AWG wire gauges with a 1/2 inch stud connection. This circular terminal features crimp termination, heat shrink insulation, and a brazed seam construction. The part is classified as obsolete, necessitating identification of active equivalent alternatives for continued procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PH10-12R-E is determined by the following critical parameters:

Primary Compatibility Criteria:

• Wire gauge range: 10-12 AWG
• Terminal type: Circular
• Stud size: 1/2 inch
• Termination method: Crimp
• Insulation type: Heat shrink
• Contact material: Copper
• Contact finish: Tin
• Insulation diameter: 0.240" (6.10mm)
• Insulation material: Polyolefin

Secondary Considerations:

• Mounting type: Free hanging (in-line)
• RoHS compliance status
• Product availability and active status

Two substitute parts meet these criteria: the PH10-38R-E (Panduit Corp) and the 8-55861-3 (TE Connectivity AMP Connectors). The PH10-38R-E differs in stud size (3/8 inch versus 1/2 inch) and is applicable only when mechanical mounting requirements permit this variation. The 8-55861-3 maintains identical stud size and all critical electrical parameters, providing direct functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred):

The 8-55861-3 manufactured by TE Connectivity AMP Connectors provides direct functional equivalence to the PH10-12R-E. This part maintains identical wire gauge (10-12 AWG), stud size (1/2 inch), terminal type (circular), termination method (crimp), insulation specifications, and contact materials. The 8-55861-3 is currently active in production, ensuring long-term availability. Both parts are RoHS compliant and share the same HTSUS classification. The minor dimensional variation in overall length (1.728" versus 1.540") does not affect electrical performance and is within acceptable mechanical tolerances for standard mounting applications.

Alternative Substitute (Conditional):

The PH10-38R-E remains within the Panduit Pan-Term® series and maintains all critical electrical parameters. However, the stud size reduction from 1/2 inch to 3/8 inch introduces a mechanical incompatibility with existing 1/2 inch stud hardware. This part is suitable only for applications where the mounting interface can accommodate the smaller stud diameter. The PH10-38R-E is currently active and ROHS3 compliant.

Compliance Status:

Both substitute parts maintain RoHS compliance and share the same ECCN (EAR99) and HTSUS (8536.90.4000) classifications as the original part, ensuring regulatory continuity.

Frequently Asked Questions (FAQ)

Q: Can the 8-55861-3 be used as a direct replacement for the PH10-12R-E?

A: Yes. The 8-55861-3 maintains all critical electrical and mechanical parameters: 10-12 AWG wire gauge, 1/2 inch stud size, circular terminal type, crimp termination, heat shrink insulation, copper contact with tin finish, and 0.240 inch insulation diameter. The part is currently active and RoHS compliant.

Q: What is the primary difference between the 8-55861-3 and PH10-12R-E?

A: The 8-55861-3 is manufactured by TE Connectivity rather than Panduit, and has a slightly longer overall length (1.728" versus 1.540"). The 8-55861-3 also specifies a thickness of 0.040 inch and uses ETP (Electrolytic Tough Pitch) copper. These differences do not affect functional compatibility in standard applications.

Q: Can the PH10-38R-E replace the PH10-12R-E?

A: The PH10-38R-E is electrically equivalent but mechanically incompatible due to the stud size difference (3/8 inch versus 1/2 inch). Use this part only if the mounting hardware can accommodate the smaller stud diameter.

Q: Are both substitute parts RoHS compliant?

A: Yes. The 8-55861-3 is RoHS compliant, and the PH10-38R-E is ROHS3 compliant. Both meet regulatory requirements for restricted substance content.

Q: What is the wire gauge compatibility for all three parts?

A: All three parts (PH10-12R-E, 8-55861-3, and PH10-38R-E) are rated for 10-12 AWG wire gauges and use identical crimp termination methods.

Q: Does the insulation diameter remain constant across all three parts?

A: Yes. All three parts specify an insulation diameter of 0.240 inches (6.10mm) with polyolefin insulation material, ensuring compatibility with standard wire sizes in the 10-12 AWG range.

Q: What is the availability status of these substitute parts?

A: The PH10-12R-E is obsolete. The 8-55861-3 and PH10-38R-E are both currently active in production, ensuring ongoing availability for procurement.
